6 Claims.

This invention relates to thread-advancing reels which may be used forthe production of a yarn store which is continuously advanced axially ofthe periphery of the reel during which time it may be subjected to fluidtreatment in the manner and for the purposes conventional in the art.

In the drawing, illustrative of the invention,

Figure 1 is a mid-section taken axially through one embodiment of thereel of this invention,

Figure 2 is a section taken on line II-II of Figure 1 and Figure 3 is across-section of a detail taken on line 1II-III of Figure 1.

As shown, the reel is embodied in a structure adapted to be supported atboth ends, though it is to be understood that, by suitable modification,it may be embodied in a cantilever form, supported at one end only ofits axis.

The reel comprises a concentric set of spaced longitudinally extendingbar members 2 which form the cylindrical periphery of a cage-like systemcomprising the end flanges 3 and 4 mounted rotatably as a unit uponshaft 5 by means of suitable bearings 6 and A male coupling memher 8 isadapted to be received within a socket of a supporting member 8a whichordinarily maintains the shaft 5 stationary. The flange 4 is providedwith a male coupling member 9 which may be provided with a projectingrib of noncircular cross-section and is adapted to be received in afemale coupling member 9a on a suitable driving shaft whereby the cagemay be rotated with respect to the shaft 5.

A second set of spaced, longitudinally extending bar members II] arearranged to alternate with and interdigitate between the bar members 2of the first set. The supporting means for the bar members I comprises apair of annular telescoping members II and I2 which are rotatablymounted on suitable bushings l3 on an intermediate eccentric portion aof shaft 5. A number of spaced radial recesses 4 extend transversely ofthe plane of juncture l5 between members II and I2 and receive ears l5which are pivotally mounted on the pins I! which extend across therecesses l4 into suitable bearing recesses at each side thereof. Theears l6 are connected to the strips I8 which in turn are secured to theinwardly extending portions I9 of the bar members ID by screws 20 and2|. The strips l3 also carry toward one end thereof depending hook-likeears 22 which have arcuate surfaces 23 bearing upon the outer race ofball bearing ears 22 and presses them against the bearing 24.

The bearing 24 is adjustably mounted with respect to a portion 51) ofthe shaft 5 by means of the bushing 42 as shown in Figures 1 and 3. Theintermediate portion 51) of the shaft 5 is concentric with the eccentricportion 5a and has a diametrally extending transverse slot 26 whichextends from the juncture of portions 5a and 5b and is disposed at anangle to the direction of offset. The sleeves 21 and 21a serve to locatethe bearing 24 axially of the shaft 5 and are slotted to permit theaxial travel of the sliding cam plate 4|! within the slot 26. A centralscrew headed rod 35 threadedly engages the interior of shaft 5 which ishollow at one end and has a foot 36 (formed by grooving out a neckadjacent to the end of the rod.) engaging a slot 31 in the cam plate 40.The cam plate 40 is cut away at 43 (Figure 3) to permit verticaldisplacement of the plate 40 with respect to the neck portion 44 of rod35 adjacent the foot 36. A bore 38 in the supporting member 8a and thecoupling 8 provides access to a screw driver or equivalent tool toadjust the axial position of rod 35 within the hollow portion of theshaft 5 and thereby move the cam plate 4|] axially also. A slot 39 inplate 40 cooperates with a transverse pin 4| through the eccentricportion 51) of shaft 5 to prevent radial motion of plate 4|] whilepermitting the axial motion. A bushing 42 mounted on the portion 5b ofthe shaft has a pair of opposed sloped surfaces which bear against thesloped surfaces of the cam plate 40 so that as the plate moves axiallythe axis of bearing 24 carried on the bushing 42 is offset from the axisof the eccentric portion 517 in a direction which is at an angle to thedirection of ofiset of the axis of portion 5b with respect to the axisof shaft 5.

A packing ring 28 may be placed between the coupling 8 and the flange 3.Also, the reel may be provided with a flexible sealing member 29 ofrubber or synthetic rubber or rubber substitute, which member may takethe general form of an annular sleeve having a ring of perforations 3Dand another ring of perforations 3| which permit the passage of screws20 and 2| respectively. The ends of the flexible sealing member 29 maybe secured as at 32 and 33 between rings 34 and the adjacent wall offlanges 3 and 4 respectively.

It should be noted that the ends of bar members l0 to the left as seenin Figure 1 are approximately in the plane of the pins so that therocking action of bar members l0 under the influence of the eccentricand askew bearing 24 24. A spring 25 surrounds the hooked portions of 55as they rotate thereabout causes alternate prorotation may be impartedto shaft 5 through coupling member 8 by providing an arrangement similarto the right of the reel as viewed in Figure 1. This rotation may be inthe same. or opposite angular direction as the rotation imparted to thereel by coupling member 9. By rotating the shaft 5 in the oppositedirection, a greater frequency of actuation of the bar members lrelative to bar members 2 is effected per revolution of the reel bycoupling 9. On the other hand rotation of shaft 'in the same directionreduces the frequency of actuation of'bar members I 0 relative to barmembers 2;

It is obvious that this reel may be converted into a cantilever formsupported at one end only. For example, shaft 5 may be extended throughflange 4 and flange 4 may be provided with a concentric sleeve carryingan annular gear by which it may be driven. The shaft 5 may then be heldstationary in suitable be rotated.

It is to be understood that changes and variations may be made withoutdeparting from the spirit and scope of the invention as defined by theappended claims.
